Original Subaru WRX STI Parts and Accessories

The Subaru WRX STI was introduced in the early 2000s as the highest-performance evolution of Subaru’s rally-inspired lineup. Built with motorsports influence, the STI featured reinforced drivetrains, performance-tuned suspensions, and aggressive styling cues. Unlike the standard WRX, the STI focused on track-ready durability, including upgraded differentials and braking systems.

Knowing Your Subaru WRX and Maintaining Peak Performance

The WRX STI was powered by a turbocharged 2.5L Boxer engine producing over 300 horsepower, paired with a six-speed manual transmission. Its driver-controlled center differential allowed adjustable torque distribution, setting it apart from many competitors.

Stiffer suspension tuning, Brembo braking systems, and aerodynamic enhancements made the STI capable on both road and track. Interior design emphasized control, featuring bolstered seats and a driver-focused layout.
